Setra's patented variable capacitance sensor features a 316L stainless steel diaphragm and an insulated electrode plate. A variable capacitor is formed between the sensor body and the electrode plate. An increase in pressure causes a slight rounding of the diaphragm, which decreases the capacitance. The capacitance change is detected and converted to a highly accurate linear DC electric signal by Setra's unique custom integrated circuit, utilizing a patented charge balance principle. Setra’s entire Ultra-High Purity series is based on Setra's proven capacitive sensing technology with highly accurate and stable voltage or current output signals that are virtually EMI/RFI immune. Setra maintains a 700 square-foot, vertical laminar flow, Class 100 clean room, where all UHP producst are carefully cleaned, tested, inspected, double bagged and back-filled with high-purity nitrogen and sealed for shipping. 0 psig, 0 psia Bar Proof Burst or Ranges Pressure Pressure -14.7 psig to: -1 or 0 to: (psi) (psi) 25 1.7 40 1500 50 3.4 75 3000 100 7 150 3000 250 17 350 5000 500 35 650 7500 1000 70 1250 7500 2000 138 2500 8000 3000 200 3500 10,000 Setra's Model 217 Transducer is designed for modular "Block" gas sticks and panels. The 217 is ideal for pressure measurement applications that require exceptional insensitivity to environmental extremes, such as temperature transients resulting from the flow of cold gas. The Model 217, available with a C-Seal or W-seal down-mount pressure port, has a small swept sensor chamber for easy purgeability. All wetted parts are 316L VIM/VAR stainless steel passivated to 5 Ra (7 Ra. max.) finish, which eliminates surface irregularities and provides the proper surface chemistry for corrosion resistance, assuring contaminant-free gas distribution. Every sensor is mass spectrometer helium leak tested to 1 x 10-9 atm.cc/sec. The 217 is offered with a 5 VDC, 10 VDC or 4-20 mA output. A variety of standard electrical terminations are offered. When it comes to a product to rely on - choose the Model 217. When it comes to a company to trust - choose Setra. ISO Certified 9001: 2000
